RFLP genetic linkage map of wheat recombinant inbred lines derived from W7984 Opata,was used to study QTL of 33 traits associated with water use efficiency.Compared with QTL map of 7 group homeologues chromosomes,the results were showed as follows:nearby the centromeric region of 1A and 1B chromosome,the gene cluster of controlling photosynthetic and root traits were located.

我们利用W7984 Opata重组近交系的RFLP作图群体，对33个与小麦水分利用效率有关的性状进行了QTL遗传图谱比较分析，结果显明：在第一部分同源群染色体（1A，1B）上的着丝粒周围，分布有控制光合作用和根系特性的基因簇。

This experiment first studied in the mature nutrient medium to increase the hormone to the porine ovocyte in vitro mature process in the chromosome configuration and the mature rate influence, by explored the porine ovocyte in vitro mature rule, enhanced in vitro raise maturity, was the ROSI technology system preparation high quality ovocyte; Then has carried on the experiment in view of the porine round sperm cell in vitro separation, through to the ROSI operation and ICSI (Intracytoplasmic sperm injection, the comparison which ICSI) operated studies has affected the ROSI operation the factor.

本试验首先研究了成熟培养液中添加激素对猪卵母细胞体外成熟过程中染色体构型和成熟率的影响，以探索猪卵母细胞体外成熟规律，提高体外培养成熟度，为ROSI技术体系准备优质卵母细胞；然后针对猪圆形精细胞的体外分离进行了试验，进而通过对ROSI操作和ICSI(Intracytoplasmic sperm injection，ICSI)操作的比较研究了影响ROSI操作的因素。

Since Watson and Crick have brought forward the model of DNA helix structure and explain about it's reproduce mechanism in molecule level, research work concerning DNA has been continuously lucubrated. However, whether translating inheritance information and rebuilding DNA molecule via menstruating DNA sequence, or to date the most compelling gene project, chromosome protract et. al, there all need a sort of molecule scissors cleaving DNA, DNA cleavage reagent. At present, tool enzyme of cleaving DNA is mostly DNA restriction enzymes founded in 70 years, which only cleave DNA at specific 4-8 base pair sequences that are usually palindromic, so this restricts the at very fast speed developing of gene technology at certain extent.

自从Watson和Crick提出DNA的双螺旋结构并对其复制机制在分子水平上进行解释后，使得对DNA的研究不断深入，但无论是通过测定DNA的序列来破译遗传信息、改造DNA分子，还是目前最令人关注的基因工程、染色体绘制等，都需要一种断裂DNA分子的&剪刀&——DNA断裂试剂，目前断裂DNA的工具酶主要是上个世纪70年代发现的DNA限制性内切酶，但所知的Ⅱ型限制性内切酶的DNA序列识别长度较短（约为4～8个碱基对），而且一般要求回文结构，这就给飞速发展的基因工程技术带来一定的限制。
